Helped with 02 sensor plugged in, TPS will be reading correct now.

Haha yeah, short memory of me me didn't help. It's just that I thought to look for any loose injector earth at the firewall end of the block, and there I saw the plug not connected.

Did it drive ok?

Yeah it drives ok, but always has. It's the miss on idle that Enoys me.
It still has the miss, but have to get around to trying dfi and coil packs.

Check spark plug gaps are correct & no sign oof arcing in/on leads & coil pack terminals...other than than all the earths on engine are clean & tight.

Pcv set up clean & working?

It's getting to the nitty gritty stuff now haha

Yip mine has a miss at times but I learn to live with it and turn the music up. You think you have it sorted then bang it does it again, I changed everything bar the wiring loom, over it, only does it at idle some times.

Have you done a compression test recently ?

I replaced the pcv valve about 8 months ago.
Speaking of coil pack terminals, my number 2 plug on the coil pack is tarnished/ slightly corroded, but all other pack terminals are nice and shinny? This is the 2nd number 2 terminal that has done this.
I think I have some spark plug photo that I checked a few months ago.
I will get around to checking the other Earth's,
I've checked the multi earth bolt beside battery, and it's nice and tight, I haven't cleaned it though.

So frustrating...

Hi woteva,
No I haven't done a compression test, but since it's been mentioned, I think it could tell a story?
I'll have to see if my mate has a compression tester

When had v6 in vp it had weird random intermittent miss...all coils,leads,everything were within spec...just had slight arc mark in inside 1 lead where it popped onto coil pack....was that aftermarket coil pack.
